ADJUSTABLE RADIATION CQNTRGL FOB BALANCED-IPRESSURE RADIATORS.

Application filed. September 26, 1924. Serial No. 740,13

This invention relates to means for controlling the heating e'li'ect o1 steam radiators of the balanced pressure type and comprises a swinging member having connection with t the interior oi? the radiator and with the drain pipe and forming the overflow for the water 01'? condensation within the radiator so that in its various angular adjustments it will cause said overiiow to take i place at different elevations and consequent ly determine the level of the conden water remaining in the radiator so that the radiation area exposed to the action of the steam may be varied to suit the require- 15? ments.

With the above and other objects in view the invention consists in the adj ustable radiation control for low pressure radiators as herein claimed and all equivalents.

.1 Referring to the accompanying drawings,

in which like characters of reference indi- 1' cate the same parts in different views,

Fig. 1 is a front elevation of a radiator provided with an adjustable radiation controlling means in accordance with this invention, parts being broken away to show the water level;

Fig. 2 is a sectional plan view thereof, and

Fig. 3 is a sectional detail of the swivel connection with the overflow pipe.

In these drawings, indicates the usual balanced pressure steam radiator receiving steam at its upper end through the steam pipe 11 and returning water of condensation through the return drain pipe 19.. Instead of the drain pipe 12 having direct connection with the bottom oi'. the radiator, the outlet pipe 13 conducting the water trom the radiator terminates in a li -coupling 1.4, to which the drain pipe 12 connects, but direct communication between pipes 13 and 12 is prevented by the presence oi a pair of overflow tubes 15 and 16, one contained within the other and both fitting within the casing formed by the T-coupling l i as will be now described.

The inner tube 15 has secured to its end a ring 17 forming a conical flange which its against a conical seat 18 provided for it around the opening into which orain pipe 12 is threaded. The outer tube 16 at its end fits around the ring 17 and within the cylindrical extension of the opening forming the conical seat 18. its edge is beveled forming a packing gland 19 between it and the said flange whereby it will be seen that the tubes are so mounted within the casing that they are capable of being turned in their seats. The outer tube 16 has openings 23 through which communication is had with i the interior of the radiator and both tubes are bent as shown, so that their outer ends swing in a plane at right angles to the axis of their pivotal seats permitting them to travel close to the front or the rear of the radiator as the case may be. The inner tube terminates just short of the outer tube and a cap 24 is threaded on the latter.

Now it will be seen that, inasmuch the water of condensation cannot pass directly to the drain pipe 12, it rises in the outer tube 16 until it overflows the outer end of the inner tube 15, which "forms an adjustable extension of the drain pipe, and the elevation of this point of overflow determines the level oi? the water remaining in the radiator and consequently the area of the radiation surface above the water exposed to the action of the steam. By swinging the overflow pipe to a vertical position the water level within the radiator will be caused to rise to its maximum with a consequent reduction in radiation area which may be such as to exclude the steam entirely. On the other hand by swinging the overflow pipe to the horizontal position shown in dotted lines, the water level will be lowered to expose practically the entire radiating surface to the action of the steam. Any intermediate adjustment of the overflow pipe will be accompanied by a corresponding change in the water level within the radiator so that the eiieetive radiation surface may be varied to suit requirements. It obvious that other means may be employed for obtaining the swivel mounting of the adjustable overflow pipe so that the only entrance to the drain pipe is through the outer end of the inner tube, but the present construction is particularly desirable for this purpose in view of the arrangement by which the tightening of the gland bushing 21 not only seals the outer tube 16 but, by forcing the inner tube 15 against its conical seat, seals it also.

The term balanced pressure as herein used is intended to apply to those heating systems in which there is no suhstentielly greater inlet pressure than outlet pressur to defeat the purposes of the invention.
